Joint DRD5-Unicorn workshop on radiation damage to quantum dots

Wednesday 26 Nov 2025, 09:00 → 18:30 Europe/Zurich

222/R-001 (CERN)

Anne-Mazarine Lyon (CERN), Michael Doser (Massachusetts Inst. of Technology (US))

If quantum dots (QD's) are to be used in HEP environments, it is important to understand their sensitivity to radiation and to be able to take possible counter-measures in case of excessive sensitivity. This workshop will discuss the state of the field and is expected to result in both a protocol for radiation tests with QD's as well as possibly a list of good practice steps to ensure their radiation hardness.

Please contact michael.doser@cern.ch and/or anne-mazarine.lyon@cern.ch for organizational matters.

This workshop is co-organised by DRD5 collaboration and the European Horizon Europe pathfinder project UNICORN (GA 101098649).
